Apple could have chosen to release maps once it was actually ready. Corrections are inevitable with something as complex as that. Releasing what should be a beta product at best is just asking for problems. On occasion I've had problems with Google maps too, so it's not like these things are perfect.
maps in Melbourne is that rather than labels showing the name of a suburb on the map, the name of the local councils are displayed (eg. Whitehorse, Manningham, Monash, Nillumbik, Banyule).
